The Atlanta Journal-Constitution reported Jackson's deal is for $12 million with $4 million guaranteed.

Jackson, 29, spent the first nine seasons of his NFL career with the St. Louis Rams, rushing for 10,135 yards and 56 touchdowns as one of the NFL's premier backs. Jackson asked for and was given the ability to void his contract with the Rams, with the goal of catching on with a contender in a featured role.

This makes Jackson a potentially ideal fit with the Falcons, who recently cut ties with Michael Turner. Jackson should see plenty of work, though expect Jacquizz Rodgers to get his touches as a change-of-pace option.

Steven Jackson through the years

Running back Steven Jackson agreed to terms with the
Atlanta Falcons this week. Take a look back at his career over the years.

Now, Jackson joins a veritable all-star team in Atlanta. The Falcons' offense was dangerous last season with quarterback Matt Ryan, wide receivers Julio Jones and Roddy White, and tight end Tony Gonzalez. If Jackson plays to his reputation, there is no ceiling.

UPDATE: The Rams released a statement Thursday on Twitter from owner Stan Kroenke, thanking Jackson for his time with the franchise.

"For nearly a decade, Steven Jackson served as an inspiration for his St. Louis Rams teammates and our fans," the statement read. "Off the field, his generosity and unselfishness improved the lives of many families in the St. Louis community. We will always be thankful for his contributions to our team and region and wish him success moving forward."
